Researchers discover molecular mechanism that helps HSV1 infect the brain

Herpes simplex virus (HSV1) infections are initiated at mucosal surfaces where the virus infects epithelial cells.

Pangolins may be the key to new COVID-19 treatments

Researchers at the Medical University of Vienna, Austria, have made an important discovery about the immune response to coronaviruses in pangolins that could point to new approaches for treating human cases of infection.

Predicting the dose for repurposing nitazoxanide in COVID-19

A new study published on the preprint server medRxiv in May 2020 reports a model that could help evolve appropriate dosage protocols for future clinical trials of the repurposed drug nitazoxanide in COVID-19 prevention and treatment. The researchers say, “It was possible to achieve plasma and lung tizoxanide concentrations, using proven safe doses of nitazoxanide, that exceed the EC90 for SARS-CoV-2.”

Patients recently recovered from COVID-19 produce virus-specific antibodies

Most newly discharged patients who recently recovered from COVID-19 produce virus-specific antibodies and T cells, suggests a study published on May 3rd in the journal Immunity, but the responses of different patients are not all the same.

COVID-19 progression linked to B cell activation

The disease course of COVID-19 is diverse, ranging from asymptomatic to fatal respiratory failure. Scientists have been working to uncover the immunological reasons behind this heterogeneity. A recent study on B cells, published on the preprint server medRxiv in April 2020, shows that extrafollicular B cells could be a marker of severe infection in the early stages, predicting the need for earlier immunomodulatory therapy.

UK-based biotechnology firm discovers potential treatments for Covid-19

A UK-based biotechnology firm has announced the discovery of two separate novel treatments for Covid-19 patients before they are put on ventilators. They are now urgently seeking funding of £4m to accelerate safety studies and clinical trials.

SARS-CoV-2 readily infects human intestinal cells in a laboratory model

A new Dutch study available on bioRxiv uses differentiated human small intestinal organoids in vitro to demonstrate that intestinal epithelium supports the replication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and elicits a strong generic immune response.

Mapping complex peripheral immune response to severe COVID-19

In a recent article publicly available at medRxiv, researchers from Stanford have presented a single-cell atlas of the peripheral immune response to coronavirus disease (COVID-19), highlighting pertinent immunological features associated with the severe forms of the disease.

Research shows how the immune system reacts to hepatitis C viruses

If a virus penetrates a cell, the immune system reacts immediately and produces the signaling protein interferon.

Goblet cells in the human nasal passage may play key role in enabling COVID-19 infections

Two significant international studies involving hundreds of scientists, including a human geneticist at the Translational Genomics Research Institute (TGen), an affiliate of City of Hope, suggest that specific cells in the human nasal passage shaped like a champagne glass, known as goblet cells, may play a significant role in enabling COVID-19 infections.

Scientists identify cells likely targeted by novel coronavirus

Researchers at MIT; the Ragon Institute of MGH, MIT, and Harvard; and the Broad Institute of MIT and Harvard; along with colleagues from around the world have identified specific types of cells that appear to be targets of the coronavirus that is causing the Covid-19 pandemic.

Research offers clues to how SARS-CoV-2 gets into respiratory tissue and exploits our defenses

What makes SARS-CoV-2, the virus behind COVID-19, such a threat? A new study, led by Jose Ordovas-Montanes, Ph.D. at Boston Children's Hospital and Alex K. Shalek, Ph.D. at MIT, pinpoints the likely cell types the virus infects.

New findings could make immunotherapy treatments effective for more cancer patients

Scientists have developed a new way to map the molecules on tumour cells that flag their presence to the immune system, according to a study published today in eLife.

22 Apr 2020

Computer simulations yield promising vaccine candidate against SARS-CoV-2

In a recent study that appeared on a preprint server bioRxiv, scientists from India designed a multi-epitope peptide-based vaccine that predicted high immunogenic response in the population.

Specialized proteins could soak up excess cytokines in COVID-19 patients

One of the defining features of Covid-19 is the excessive immune response that can occur in severe cases. This burst of immune overreaction, also called a cytokine storm, damages the lungs and can be fatal.

Tumors commandeer cell death pathway to avoid immune system attack after radiation

Cancer cells avoid an immune system attack after radiation by commandeering a cell signaling pathway that helps dying cells avoid triggering an immune response, a new study led by UTSW scientists suggests.

Molecular pathway responsible for TNBC's progression and spread identified

Immunotherapies have revolutionized treatment for people with a variety of cancers. But when given to those with triple-negative breast cancer, a particularly aggressive form of the disease, less than 20% respond.

Researchers discover inflammatory mechanism that contributes to autoimmune diseases

The protein STING (Stimulator of Interferon Genes) is a critical component of the body's innate immune defence system, but can also contribute to chronic autoimmune and autoinflammatory diseases.

Researchers identify the most common characteristics of fatal COVID-19 cases

In a new study, researchers identified the most common characteristics of 85 COVID-19 patients who died in Wuhan, China in the early stages of the coronavirus pandemic.

Immunotherapy may benefit mCRPC patients with specific markers of immune activation

Although metastatic castration-resistant prostate cancer typically has limited response to immunotherapy, a subset of patients with pretreatment evidence of active T-cell responses in their tumors experienced prolonged survival following treatment with ipilimumab in a Phase II trial at The University of Texas MD Anderson Cancer Center.
